To all wiz/0m, it may concern:

Be it known that I, CLINTON A. CHAMBER- LIN, a citizen of the United States, residing at Detroitin the county of Wayne and State of Michigan, have invented certain new and useful improvements in Building-Valls, of

'which the following is a speciiication, reference being had therein to the accompanying drawings. The invention relates to building-walls of that type commonly knoWnas two;.piece construction and in which ,ahollow wall is l produced by` two series of blocksforming, re-

spectively, the inner and outer faces and having projections bridging across the hollow space between.

The present construction is one which may be built from a comparativel few simple forms of blocks, so as to rneet a l the requirements of ordinary building construction.

The invention therefore consists in the pe culiar construction and combination of blocks to form a building-wall, as hereinafter set forth.

` `buildin ocks are formed fromr a plastic "materia such as a mixture of sand and cement, and are generally manufactured by hand-operated moldin -Inachines located at the oint Where' the building is to be erected. To acilitate the work of molding the blocks, it is desirable to limit ,the blocks to as few distinct forms and sizes as ossible, and it is also advantageous to have orms which maybe ments.

molded without coring., In tlie resent construction only four types of bloc s are used, and these for Walle of different thickness are only altered in one dimension. Moreover,

all fourtypes of block may be easily molded on a single machine and by simple adju`st- The forniti block bien is' used in the t0n-i struc'tion'fof agsimple straight wall, such as' that designated'by Ak andvas illustrated in Fig. 6, is Lsha ed, comprising a long side a and a shorter1 s i e t. The long' side a is usually the standard length of full block; but where required this may be shortened to three-fourths, one-half, one-fourth, or any other division required. The short arm b may be varied in length according to the width of the wall desired, and the change in the length of this arm does not require any ycorresponding change in the length of the :long arm, as will be explained hereinafter. A straight wall formed with these L-shaped blocks is shown in the upper ortion of Fig. 1, and the blocks are assemble with those forming, res ectifvely, the outer and inner faces of the Wa l oppositely arranged-c'. e., their shorter arms t extend, respectively, inward and outward.` l This construction of straight wall may be extended to an indefinite length by the use of this one form of block A; but when it is necessary to turn a corner other forms are required in addition. Thus on the formed by an Lshaped block B, in which the short arm is one-half the length of the long arm and turns the corner on the outer face of the wall. The inner face of the wall is oompleted at the corner by the insertion of a T- shaped block C, which, as shown in Fig. l, is arranged with the head of the T parallel to the lon side of the wall and the stem of the T para lel to the turned corner. A straight blockD also employed in connection with the T-shaped block on the inner face of the turned portion of the wall, after which the wall may be extended by the use of L-shapeol` blocks alone.

For turning the opposite cornerthat is, on the right-hand side of Fig. l-another form Olrblock E is employed in connection with those already described and which is of U shape, having two short arms t tz at its opposite ends. This U-shaped block may be arranged at any point des1red in the straight portion of the wall intermediate the corners thereof, and its function is to change the directions of the Ls. Thus when the corner is reached the L-shaped block forming the outer face of the wall is properly arranged to turn the corner, as illustrated at F on the right-hand side of Fig. 1. The inner face of the wall is completed `at the corner by a T- Aillustrated in l* 1g. 4.

wall may bebuilt with any number of rec- 1 tangular turns therein and Without the necesleft-hand. upper side of Fig. 1 the corner is shaped block C, similar to the block C, but` By using the system above describedA the1 IOO AIIO

sity of employing blocks of any other form Where, however, it 1s'.

than those described. desired to form chimneys or pilasters or Where the Wall turns-at any angle other than f a rectangle, blocks of slightly-modified form are necessary. Thus on the lett-hand side of Fig. 1 a single-ihre chimney is formed bya block G, which is of the U form, similar tov the block E, but having .its short -arms t3 extended, so that when arranged to abut against Y the blocks ormin one face ofthe Wall a projection is formed eyon'd the opposite face of,

the Wall.

In Fig. 3 a-,modiication is illustrated in?, which a two-fine chimney is produced by the` combination of a isi-shaped block H, having extended short arms and a lil-shaped block- I, one of the short erms of which is 'corre- 'oint of this first course, which may be done y'placing the L and U sha ed bloclrsin the straight Wall to overla `t eA blocks of the lower course by one-hai their len th. The bonding at the corners is produced .y reversf ing the Ls,'sothat the short arm inthe superposed course is arranged over the longarm of the lower course. The inner corners are Vbonded by changing the position of the 't'- shaped blocks 5C so that the stem ot the superposed block Will overlapthe head of the lower block, this arrangement being illustrated in Fig. 2. I

it has been stated that la straight wall formed of the L-shaped blocks may -be eX- tended with the Ls oppositely arranged by the employment of intermediate Us. In order that this 'may be done, l preferably arrange the blocks 'respectively torn ing the inner and outer faces of the wall so as to overlap in the manner illustrated-that is, instead o lbeing arranged so that the joint between blocks in jln'e face is at the center of the blocks in the opposite tace the joint is removed ironi said center by the thickness of the block. Stated in other Words, the inner face of the short arm of the L forming one face di the Wall A is arranged at the center of the L forming the opposite face of the Wall. Thus the thickness of the/short arm is alwa s arranged upon one side of the center of the o posite block, and this holds true when U- s sped blocksvare substituted for Ls, the

erases only difference being that this shifts the arm to the opposite side ol the center.

, it will be understood that all of the forms of' blocks which have been referred to ma be bonds between said faces, the :Us in diierentv longitudinal portions of said Wall being o osite T arranged and U-shaped blocks uniting said portions of the Wall formed by the oppositely-arranged 2. A. hollow building-Wall comprising t.-

shaped blocks arranged to vform With their long arms respective y the outer and inner faces of the -Wall and their short arms bonds between said faces, the opp osite corners of said Wall being formed by oppositelyarranged Ls, and lol-shaped blocks arranged intermediate the- L-shaped blocks extending from said opposite corners.

3. A hollow building-Wall comprising L- shaped blocks arranged to form with their long arms respectively the outer and inner faces of the Wall, and With their short arms bonds between said faces, the outer corner of said wall bein formed by one of said Ls and a i'-shaped `b.ocl:. for forming the inner corl ner.

et. A hollow building-Wall comprising L- shaped blocks arranged, to form with their long arms respectively the outer and inner faces of the Wall and With their short arms bonds between said faces, an L-shaped block having the short arm thereof one-half the length ofthe long arm forminfy the outer corner of the wall and a T-shaped block 'forming the inner corner.

5. A holler.r building-wall comprising L- shaped blocks arran ed to form with their long arms respective y the inner and outer faces of the wall and their short armsbonds between said faces, an IIL-shaped block 'forming the ont-er corner of said wall, and an inner corner formed by' a block having integral bonds extending to the outer face m line respectivelywith the adjoining inner faces.

G. In ahollow building-Wall vhaving -its I ing its 'outer face formed by' ln-shaped blocks' provided With leng and short arms reversed in altenate emjn'ses, and T-shaped blocks forming the inner corner with. bonds in line with the adjoining inner faces, said blocks beingananged in alternate Gouines with vtlieir beads and stems reversed.
